I have been using only lee presses for over 20 years with no problems what so ever , first off how much are you going to be loading //2000 rounds a year or less go lee - 2000 rounds or more go with the dillon no question it is top of the line. are you going to use it for only 44s or you going to change cal.- i like the chang over time of the lee
A friend of mine has a 550 but only uses it for .40 s&w and uses a lyman for everything else
